I have a static IP provided by the administrator of my Linux CentOS 6.5. The problem is that while I can ping this machine, connect to it and use it to access the internet from within my network, I can neither ping it nor otherwise access this IP from outside the network.
What is the problem? I have disabled the Firewall of CentOS and still can only use it from internal to external and not vice versa.
What should I do?
